3mm omnidirectional microphone capsule with pre-attached 25mm leads for easy integration, ideal for Bluetooth earphones and compact devices.
The ECM-B3015AL-42-L25 is a 3mm omnidirectional microphone capsule designed for easy assembly in compact devices like Bluetooth earphones. Equipped with pre-attached 25mm leads, this version reduces assembly time and ensures consistent quality through professional soldering and strict quality control.
Like its counterpart, this capsule features a custom Korean mic core and dual-capacitor interference resistance for stable performance. Its Japanese TOA diaphragm enhances durability and ensures reliable operation from -40℃ to +85℃.
For customers who prefer to handle soldering themselves or require further customization, the ECM-B3015AL-42 (non-soldered version) offers the same performance and flexibility. Custom soldering services are also available upon request.
